Plastic Waste Transformed into Edible Food for Space Missions and Earth Applications
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: Scientists have developed technology to transform plastic waste into edible food using microbes and 3D printing, offering dual solutions for space mission sustainability and Earth’s plastic pollution crisis.
📈 One key stat: The technology enables astronauts to convert plastic waste into customizable food options on long-duration space missions, potentially eliminating the need for regular resupply missions and conserving valuable resources.
💬 One key quote: “The technology employs a specially designed extruder that builds textures and aligns fibers to create food products from the biomass produced by the microbes.”
1️⃣ The big picture: Scientists are exploring an innovative solution to two major challenges: sustaining astronauts on long space missions and addressing Earth’s plastic waste crisis. Researchers at Michigan Tech have developed a process using microbes to break down plastic waste, converting it into biomass that can be harvested as food. Ohio-based startup Beehex is applying this technology through bioreactors that transform plastic into 3D-printed meals with customizable textures and flavors. This technology is particularly valuable for space travel where traditional cooking is impractical and resupply missions are costly, while also offering potential applications for sustainable food production and waste management on Earth.
2️⃣ Why is this good news: This breakthrough creates a circular economy model by repurposing waste materials into valuable resources. The technology addresses both the mounting plastic pollution crisis and the challenge of feeding people in resource-limited environments. For space exploration, it reduces dependency on Earth resupply missions and extends mission capabilities. The customization possibilities through 3D printing mean astronauts can enjoy varied meals with appropriate nutrients rather than monotonous space food. Beyond space applications, this innovation could transform waste management systems globally, potentially creating sustainable food sources for populations in need.
3️⃣ What’s next: Researchers must continue refining the process to ensure the resulting food products meet federal safety standards. The Department of Defense has shown interest in funding further research, though NASA has yet to commit to integrating these systems into their missions. The technology must overcome logistical challenges related to the machinery’s complexity, especially given the limited space available on spacecraft.
